Preface

EagleBurgmann in profile

A sealing provider you can count on

A sealing system, consisting of a mechanical seal and an associated supply system that is balanced by individual applications, is the utmost guarantee for a reliable sealing point and uninterrupted pump service. The performance of the seal is greatly influenced by the environment around the seal faces, making the provision of suitable, clean fluids as well as a moderate temperature an essential topic.

EagleBurgmann is one of the internationally leading companies for industrial sealing technology. Our products are used wherever safety and reliability are important: in the oil and gas industry, refining technology, the petrochemical, chemical and pharmaceutical industries, food processing, power, water, mining, pulp & paper and many others. More than 6,000 employees contribute their ideas, solutions and commitment towards ensuring that customers all over the world can rely on our seals and services.

More than 21,000 EagleBurgmann API-seals and systems are installed world-wide.

This guiding booklet provides a condensed overview of all piping plans established by the API 682 4th edition guidelines. Each illustrated piping plan is briefly described, and a recommendation that considers the media characteristics in terms of the relevant application and corresponding configurations is given to help you reliably select your sealing system.

EagleBurgmann and API 682

We offer our customers the widest product portfolio of seals and seal supply systems according to API 682 4th edition.

EagleBurgmann SPB6 seal supply system Plan 53B

Furthermore, we have enriched this booklet's content by providing clues – so-called ‘remarks and checkpoints’ – where we share the experiences we have gained from multiple equipped plants.

applications must be calculated very carefully. Minimum orifice size should be 3 mm (1/8"). Throat bush clearance and orifice sizing together both ensure the proper flow of flush fluid to the seal. Always check the difference between the discharge and the seal chamber pressure.If the difference is too low, Plan 13 must be preferred. Use for media with solids or abrasives or polymerizing media to be avoided. Orifice clogging can be confirmed by checking pipe surface temperatures upstream and downstream of the orifice.

temperatures is an indication of proper flow. Ensure that the barrier pressure is always higher than the seal chamber pressure by at least 1.4 bar (20 PSI) (for piston ratio selection). Since there is less barrier fluid volume in the accumulator, heat dissipation is very much a function of the cooler efficiency. Ensure that the seal chamber reference line is not choked and that it is connected to the downstream of the accumulator. Ensure proper heating or cooling of the reference pressure line if necessary.
